1) Possible reasons why the indicator lamps light up
X1) The vehicle is equipped with ASR:
There is a malfunction that affects only the ASR system. The ABS and EDL systems are not
deactivated. Check DTC memory page 01
-97
.
ASR is switched off via the traction control button. If the traction control indicator light does
not light up in this case, check the switch and the indicator light, carry out the "Electrical test",
steps 21 and 22 page 01
-68
.
ASR is in adjustment mode. The traction control indicator light blinks 3 times per second.
Short circuit to B+ in the traction control button: The traction control indicator light switches off
five minutes after ignition is switched on.
The lamp remains constantly lit after ignition is switched on, but none of the above mentioned
conditions are true. There is a short to Ground (GND) in the wiring that controls the traction
control indicator light between terminal 31 of the ABS control module -J104- and the
instrument cluster.
There is an irregularity present or a complaint has been made. The indicator lamps go on
during the self-test and then go out. The possible causes are as follows:
The DTC 00526 "Brake light switch -F-" is stored in DTC memory , check DTC memory
page 01

.
The DTC 00668 "Vehicle voltage terminal 30" is stored in DTC memory , check DTC memory
